ghci: can't load module BitSet, and some others

[Marc Weber]

Hi.

I'm totally puzzled:
ghc-pkg describe ghc shows BitSet as exposed module.
When grepping the whole ghc source code the only occurance I can find is
in the package.in file for the ghc package.
But that't it
Trying to load it using GHC-api or ghci fails ?
Is this module depreceated and only there for compatibility reasons?

darcs changes reveals:

  * remove BitSet, it isn't used
So is it time to remove it completely?

I can't load all these modules:

BitSet
FieldLabel
IlxGen
Java
JavaGen
PrintJava
RegisterAlloc

So what's wrong here?

Sincerly
